by "changing mind" and "replacing heart".
And I presume that you know how creative are EXISTING computers in getting out of multidimensional labyrinths, in playing chess and other complex logical games, in playing strategy games, in regulating complex street traffic, in fuzzy keywords database search engines, in composing melodies, in writing poetry, in analysing DNA similarities, in creating cartoons and movies, etc, etc.
Download chess software and let your computer play with itself - it is cool experience to see how fast and creative are the moves of "both sides".
Robots already can, physically play piano watching sheet music (and the sheet music can be created and written by another robot), they can physically oil paint and draw creating both abstract and realistic paintings, they can play simple ball games, etc.
Robots and computers already easily outperform humans in most of single human brain functions - in calculation, in memorizing/ recalling/ searching information, in logical analysis, in various "mental modelling" of reality, in expert advising, and many other tasks.
Sure it is easy to add emotions to computer software. Display "I am sad" or gloomy face every time negative information is entered into computer or some particular situation is analysed "negative" by it, and joy face if the result is positive. Add t=rmd(N) (random number) in the program to interrupt it at time t and switch randomly to another task - and you have computer with built-in ADD (attention deficit disorder). Display "Eurica" each time a problem is solved or certain information is found. Add a string into code to moan loudly when a problem is too complex or if it takes too long to calculate. Make it say "Lunch time" at 12:00 (and stop calculating till 13:00), and shut down automatically at 17:00 displaying "Honey, I am home". Add laughting sound (if entered data are inconsistent, or the result is way out of expected range). Add snoring and "Do not disturb" screen saver between 1 am and 7 am.
The more emotions and human-specific reactions you add, the closer to real human it will look and act like.
